Muffler delete vibration and drone
 

What can make it less have less cabin drone and vibration?

Could you wrap the pipes with heat wrap? Any suggestions?

Wrapping the pipes will get rid of some of the sound but you'll probably be disappointed by how little good it does. Your best bet is to install sound-deadening material (eg, GTMat) in the interior.

Dynamat under the carpet in the hatch would help probably. As for the drone, adding a couple of resonators would help.

1. Sound deadening in the hatch - Dynamat
2. Have resonators welded into the new piping - Vibrant
3. Put your muffler back on

These cars drone because of a serious lack of sound deadening in the interest of weight savings, even with full brand-name exhaust systems. It's why you can hear the gear lash and every other little noise the transmission makes. If you don't want to put the muffler back on or buy resonators to add to the muffler delete pipes, pick up some Dynamat, remove the hatch interior plastics, and apply it to the chassis.

"3. Put your muffler back on"

Someone did a post a while back about adding pipe 90 degrees to the tail pipes to cancel the drone. He used science and everything.
As I remember it, he had a drone between 2k and 3k rpms, and calculated he needed to add a 19 inch long capped piece of pipe to each tailpipe to cancel it. The way it was described, it sounded like each different setup (brand, components used, etc.) would need to be calculated individually to get the full benefit. The calcs were based on the sound frequency of the drone.
It also sounded like you would need some fairly sophisticated equipment to measure the sound.

An audio frequency meter is not expensive nor is it difficult to use. You can buy a stand-alone meter, download an app for your smart phone, or a musical instrument tuner might do the job (most are geared toward the "open" notes an instrument uses, so may not work).

Would the drone and vibration cause damaged down the road?

Everything in your cabin will buzz in about 5-10K miles.

I think you would get tired of the noise before the could be any damage done. It would take a very long time for that mild of a vibration to cause significant damage to anything but your nerves.

Stuck the muffler back on. Feels so much better.

Go figure.:tup:

Lol. That's the main reason I have kept my stock exhaust.

Shameless plug
You know... I have an AAM axleback for sale. Just sayin ;)
No drone, or vibrations. You can add to it as your budget allows it.

Lol. Good shot.
